AFR 185 spring upgrade

[jruppert]

I have a set of these heads for my 347. I called AFR today regarding upgrading my springs for a larger cam or 1.7's. He said the stock springs are good for .550. My cam is at .542 and he said he recommended changing them. However he said that they charge around $180 when you purchase heads because they change to a different spring also. He said that if I were to buy the parts now it would cost me over $400 and that I was on my own. What is the deal with that? Has anyone ever changed the springs without the hassle and the hefty price tag?

I agree get Ed's PS2 or PS3 springs (what ever one will match your cam) and get some Viton seals, around $200 total shipped.

Thanks for your help. I am rather curious at which ones to purchase. I have a 347 with the 185's and a trick flow stage 2 cam at .542 lift. I currently am running stock 1.6 rockers but want to upgrade to roller. If I go roller I dont know if I should go 1.6 or 1.7. Do you guys have any thoughts on this? Would the 1.7 be too much for me? I know I have the clearance in pistons to go the 1.7

Use Ed's recommendation, I would ask him about the rockers also. I am not sure how the TFS 2 reacts with a 1.7, I only have expierence with the 1.6's on that cam.

Ed can hook you up with a set of Scorpion rockers also, very nice pieces $200
